Dublin Airport & CO2 – a NERDs view
Passenger limits can’t work due to population growth and the general principle that transport hubs work best at scale, the more flights through Dublin the less CO2 we will emit with direct routings. My view is that we should implement carbon budgets for flying, and make the carbon cost and tax on flying visible to consumers. Its not enough to ‘offset’ your emissions when buying the ticket, show us the actual kg CO2 inclusive of radiative forcing (freely available via ICAO[2] and others for CORSIA[3]). That is we need to put limits in terms of CO2 budgets not passenger numbers.
